WILLIAM VOSSELER, OF CINCINNATI, OHIO.

LIQUID-COOLER.

To all whom it may concern:

Be it known that I, WILLIAM Vossnnnn, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Liquid-Coolers, of which the following is a full, clear, and, exact description, reference being bad to the accompanying drawings, forming a part of this specification.

The object of my invention is to provide a strong and eflicient cooler, through which beer or other like liquids are passed when pumped from containers to point of service.

The difficulty in beer coolers, which usually comprise a series of coils or plates ar ranged in a receptacle into which is run ice or cooling brine, is to get a structure of coil which is strong and durable, and still permits of the regulation of flow of the beer so as to present all parts of it to the chilled surface of the coil. Some coolers accomplish these purposes but still do not permit of the insertion of ice between the coils.

It is the object of my invent-ion to provide a cooler which combines all of these advantages, and this I accomplish by that certain construction and arrangement of parts to be hereinafter specifically pointed out and claimed.

In the drawings, Figure 1 is a central vertical section of my improved cooler. Fig. 2 is a plan view of the coil through which the liquid passes. Fig. 3 is a vertical section through one of the coaxial ring shaped pipes and the strap, on the line 3, 3, of Fig. 1.

1 is a tank or receptacle of any desired shape or size, and made water-tight to hold ice water, brine or cracked ice. Within this reservoir are arranged a series of co-ax1al ring shaped pipes 2. Any number of these may be used, although for ordinary use five are employed. The pipes are hollow to permit the passage of the beer, which may enter either end by one of the beer pipes 3, 3. The ring pipes are spaced apart and held one on top of the other by the legs or posts 4, 4, two of which preferably are placed between each two ring pipes. These legs may be and are preferably soldered or otherwise firmly secured to the ring pipes, half of each leg on each ring pipe and so placed that the two ends meet upon setting up. The bottomring pipe is placed on a tripod stand comprising the three legs 5, 5, 5, and the metallic band Specification of Letters Patent.

6, with upwardly extending ends 7, 7. For the purpose of the more secure attachment of the band to the lower ring pipe, I provide the clamp screws 8, 8.

The inner construction of each ring pipe comprises an inlet pipe 9, an outlet pipe 10, in close proximity to each other and a wall or abutment 11 between them. It is obvious that if the beer is forced in at 9 in Fig.2, it will pass out at 10; or if it is forced in at 10, it will pass out at 9. For this reason, all my rin pipes may be constructed alike within, which goes greatly toward the cheapness of construction. It is only requisite to alter each time the position of the openings. In one case the left hand pipe is down, and in the next it is up. Therefore by arranging the ring pipes one over the other in such position each to each, that the point of outlet of one will coincide with the point of inlet of the other, and then connecting the pipes by providing screw-threaded male and female ends 12 and 13, and screwing the ends one into the other, I then obtain an altered flow of beer in each ring pipe. By thus altering the flow, the beer is churned so that all portions reach the surface of the pipes. In casting the ring pipes, an inlet is left in the side of each coil, each finished casting therefore having the tubular lugs 14 in the same place on its outer circumference. A strap 15 of sufiicient length to extend the distance of all the ring pipes used is provided with slots properly spaced to receive the lugs on each ring pipe. This strap keeps the ring pipes in perfect alinement and saves chance displacement liable to cause leaky joints. To hold the strap in place, washers 16 are provided that extend over the outside surface of the lugs, and these washers 16 are held in place on the lugs by the plugs 17 screwthreaded to screw into them. These plugs may be withdrawn for cleansing or flushing out the separate ring pipes.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1.. In a device of the character specified, a receptacle for a cooling medium, a series of coaxial ring shaped pipes in said receptacle, coinciding legs on each of the series, an inlet and an outlet for each pipe arranged near to each other, a wall between the inlet and outlet, the inlet of each one of the series of pipes in opposed relation to that of the next adjacent pipe, and connection between receptacle for a cooling medium, a series of,

co-axialring shaped pipes in saiclreceptacle,

coinciding legs on each of the series, an ini let and an outlet for each pipe arranged near to each other, a Wall between the inlet and outlet, the inlet of each one of the series of pipes being in opposed relation to that of the neXt adjacent pipe, and connections between the inlets and the outlets in the series, and a strap for maintaining the pipes against displacement, With means for mounting said strap on each pipe and means for mounting the bottom pipe above the lower surface of the receptacle. 7
